MC74ACT350
4ĆBit Shifter
With 3ĆState Outputs
The MC74AC350/74ACT350 is a specialized multiplexer that accepts a 4-bit
word and shifts it 0, 1, 2 or 3 places, as determined by two Select (S0, S1) inputs.
For expansion to longer words, three linking inputs are provided for lower-order
bits; thus two packages can shift an 8-bit word, four packages a 16-bit word, etc.
Shifting by more than three places is accomplished by paralleling the 3-state outputs
of different packages and using the Output Enable (OE) inputs as a third Select
level. With appropriate interconnections, the ′AC/ACT350 can perform zero-backfill,
sign-extend or end-around (barrel) shift functions.
• Linking Inputs for Word Expansion
• 3-State Outputs for Extending Shift Range
